In the Corporate portal, you open the wizard under Issuing & Payments via Add Configuration and choose AirPlus as the payment source.
For an AirPlus configuration you enter a name, the business unit, the account number and the financial account type (Procurement or BTM Financial Account).
You then define for each reporting field (for example cost center, employee number, project number, department code or internal account) whether it is Not Used, Optional or Mandatory, and map it to the matching data field of your company. This way the right values automatically end up on your statement. Fields such as order number, departure date and destination are mapped automatically from the transaction.
